From e424bee248c38266c6057d43f3e350072fc41c5d Mon Sep 17 00:00:00 2001 From: Thomas Egerer Date: Mon, 25 Jan 2016 12:58:44 +0100 Subject: [PATCH] ipv4+ipv6: Make INET*_ESP select CRYPTO_ECHAINIV commit 32b6170ca59ccf07d0e394561e54b2cd9726038c upstream. The ESP algorithms using CBC mode require echainiv. Hence INET*_ESP have to select CRYPTO_ECHAINIV in order to work properly. This solves the issues caused by a misconfiguration as described in [1]. The original approach, patching crypto/Kconfig was turned down by Herbert Xu [2].
